Fig. 2 is the schematic diagram of the first preferred form for the circuit from WIFI or other RF signals collecting energy constructed according to the invention.Comprise the antenna 2 receiving RF signal (such as WIFI signal) according to the energy acquisition circuit of this first embodiment, and convert described RF signal to the signal of telecommunication, the described signal of telecommunication is provided to the input of RF-DC rectifier circuit 12 by transmission line or cable 4.RF signal is converted to the DC(direct current of its output by rectifier circuit 12) signal.This DC signal is provided to first memory part 14, and it is 2F(farad preferably), 2.5 volts of ultracapacitors.First memory part 14 stores thereon and gathers the electric charge of (DC) signal through rectification that free rectifier circuit 12 exports.

The DC signal exported by rectifier circuit 12 is also provided to the input (pin 3) of the CMOS microcontroller 16 based on flash memory, CMOS microcontroller 16 preferably has by Microchip Technology Inc.(Chandler, Arizona) the Part No. 12F683-0847 that manufactures.Microcontroller 16 is used as charging circuit and controls, to prevent the over-charge of lithium battery electricity of the second memory part 18 be used as in energy acquisition circuit.

Voltage on ultracapacitor 14 is also provided to the input of first order DC-DC converter circuit 20, and described first order DC-DC converter circuit 20 is served as charge pump or in other words served as step-up voltage regulator and battery management circuit.First order DC-DC converter circuit 20 is preferably by Maxim Integrated Products(Sunnyvale, California) the Part No. MAX1672 that manufactures.

When the voltage on ultracapacitor 14 reaches specified level (such as about 1.5 volts) of the input being provided to microcontroller 16, microcontroller 16 exports (pin 5) upper generation pulse signal at it, described pulse signal is provided to the enable input of first order DC-DC converter circuit 20, so that the voltage making the converter circuit 20 serving as charge pump be inputted increases to its about 4.5 volts of exporting from about 1.5 volts.If the voltage on ultracapacitor 14 is lower than predeterminated level (such as 1.5 volts), then microcontroller 16 does not provide pulse signal to the enable input of first order DC-DC converter circuit 20 thus effectively stops converter circuit 20 to operate, in order to avoid exhaust the electric charge on described ultracapacitor 14 when the charging of ultracapacitor is insufficient.

The output of first order DC-DC converter circuit 20 is provided to the input of second level DC-DC converter circuit 22, and described second level DC-DC converter circuit 22 is preferably the integrated circuit identical with first order DC-DC converter circuit 20 and has Part No. MAX1672.Again, the preferred voltage in the output of first order DC-DC converter circuit 20 is about 4.5 volts.

As can be seen from Figure 2, described energy acquisition circuit also comprises for providing and the USB charger port of connection of external voltage source (preferably about 5 volts of DC) or connector 24, to utilize the laptop computer that can be connected to USB charger connector 24 or other devices for its like that preferably lithium polymer battery just as will be explained of inner second memory part 18() charging.+ 5 volts of input pins of USB charger connector 24 are connected to the connection between the output of first order DC-DC converter circuit 20 and the input of second level DC-DC converter circuit 22.

Second level DC-DC converter circuit 22 serves as the step-down voltage transducer/adjuster of low pressure drop, 4.5 volts (or the 5 volts of DC signals be provided in from external source USB charger connector 24) from first order DC-DC converter circuit 20 are transformed into 3.7 volts of DC signals in the output of second level DC-DC converter circuit 22.This output voltage of second level DC-DC converter circuit 22 is provided to the positive side of the lithium polymer battery 18 of a part for forming energy Acquisition Circuit, the minus side preferably ground connection of described battery.Described lithium polymer battery is preferably used as 3.7 volts, 1.5 amperes batteries of second memory part 18, and second memory part 18 to be charged or by the outside DC power source charges being connected to USB charger connector 24 from the voltage changed through rectification and DC that the RF signal that received by antenna 2 is generated by energy acquisition circuit.

Voltage on lithium polymer battery 18 is monitored, in order to avoid exceed approximate 3.7 volts.The positive side of lithium polymer battery 18 is connected to the feed back input (pin 1) on microcontroller 16, to limit by energy acquisition circuit evolving and to be provided to lithium polymer battery 18 and to be provided to the voltage of the external electrical device 8 be connected with energy acquisition circuit.When voltage on the feed back input of microcontroller 16 reaches predetermined threshold voltage (such as 3.7 volts), microcontroller 16 stops in its output being connected to the enable input in first order DC-DC converter circuit 20 (pin 5) and provides pulse signal, to prevent the first order DC-DC converter circuit 20 from exceeding the predetermined voltage conversion limit as charge pump operation.When the voltage on lithium polymer battery 18 fall described predetermined threshold voltage (it is provided to the feed back input of microcontroller 16) below time, microcontroller 16 provides pulse signal again in the output that it goes to the enable input of first order DC-DC converter circuit 20, thus converter circuit 20 recovers the operation as charge pump the input voltage provided thereon is increased to approximate 4.5 volts.But, if the voltage on ultracapacitor 14 is lower than predetermined threshold voltage (such as 1.5 volts), then can not provide pulse signal from microcontroller 16 to the enable input of first order DC-DC converter circuit 20.

The positive side of lithium polymer battery 18 is connected to the input of the third level DC-DC converter circuit 28 of also serving as charge pump by the single-pole single-throw switch (SPST) 26 that user controls.Third level DC-DC converter circuit 28 is preferably utilization to be had by Texas Instruments(Dallas, Texas) integrated circuit of Part No. TPS61200DRCT that manufactures realizes.The voltage (3.7 volts) that lithium polymer battery 18 is provided to the input of third level DC-DC converter circuit 28 by third level DC-DC converter circuit 28 increases to its approximate 5 volts of DC exported.The output signal of third level DC-DC converter circuit 28 is provided to the special pin (+5 volts of DC pins) on USB out connector 30, another special pin ground connection of described USB out connector 30.Standard USB cable 10 can be utilized by external electrical or electric device 8(such as cell phone, PDA, MP3 player, video camera etc.) be connected to the USB out connector 30 of energy acquisition circuit, thus energy acquisition circuit of the present invention can be powered for the battery charging of external electrical device 8 or for the external electrical device 8 being connected to described energy acquisition circuit by user.

Referring now to Fig. 3 of accompanying drawing, show the block diagram of the second preferred form of the circuit of energy acquisition device of the present invention.Preferably use multiple broad-band antenna 2, each broad-band antenna 2 is preferably identical.In a kind of form of the present invention, employ four broad-band antennas 2a, 2b, 2c, 2d, and each broad-band antenna 2a-2d is positioned at the outer cover 32 of energy acquisition circuit especially, thus each antenna 2a-2d can receive sent WIFI or other RF signals, and no matter the layout of outer cover 32 is how.Preferably, each broad-band antenna 2a-2d can receive the signal from about 500MHz to about 2.5GHz.

Even more preferably and as shown in Fig. 5-10 of accompanying drawing, four monopole broad-band antenna 2a-2d are placed on the inner surface of transparent or semitransparent capping 34 of outer cover 32.Capping 34 by pivot approach at it while be attached to the main body of outer cover 32 or the corresponding side of base 36 or top margin, thus can by its respectively away from and top surface near main body or base 36 raise and reduce, therefore cover and expose the solar cell 40 that the opening by being formed in the top surface 38 of main body or base 36 exposes.Although four monopole antenna 2a-2d will receive RF energy described in when capping 34 is disposed in its lower position thus covers the solar cell 40 of outer cover 32, but when capping 34 be such as disposed in as shown in Fig. 5 of accompanying drawing elevated position time, described four monopole antennas will receive the RF energy sent from RF source or WIFI source more effectively.The various features of the outer cover 32 of energy acquisition device of the present invention will be described in further detail.

Each antenna 2a-2d in the middle of described multiple antenna is coupled to corresponding voltage multiplier/full-wave rectifier circuit 42, and what go out as shown in Figure 3 is such.More particularly, each voltage multiplier/rectifier circuit 42 comprises a voltage multiplier, thus WIFI or the RF signal received by the respective antenna 2a-2d be coupled with it is converted to the DC voltage that its amplitude such as doubly increases to several times (such as 4 times, 6 times or 8 times).

More particularly, the first antenna 2a is coupled to the first multiplier/rectifier circuit 42a, WIFI or the RF signal that the first antenna 2a receives is converted to the DC voltage such as doubly increasing to 4 times, 6 times or 8 times by it.As the result of institute's detection signal of the first antenna 2a be coupled with it, the DC output voltage of the first multiplier/rectifier circuit 42 is provided to first branch road (see Fig. 3) of node A and capacitor C39.

Second multiplier/rectifier circuit 42b and the first multiplier/rectifier circuit 42a is very similar.Second multiplier/rectifier circuit 42b converts WIFI or the RF signal received by the second antenna 2b be coupled with it to the DC voltage doubly increasing to desired multiple (such as 4 times, 6 times or 8 times), and this voltage is provided to first branch road of Node B and capacitor C34, second branch road of capacitor C34 is connected to first branch road of node A and capacitor C39.Therefore, the output voltage of the second multiplier/rectifier circuit 42b is just effectively super-imposed on the voltage that exports at the first multiplier/rectifier circuit 42a.

Three multiplier/rectifier circuit 42c is similar to the second multiplier/rectifier circuit 42b, and its mode being coupled to third antenna 2c is identical with the mode that the first and second multipliers/rectifier circuit 42a, 42b is coupled to first and second antenna 2a, 2b respectively.Again, the DC voltage that three multiplier/rectifier circuit 42c exports is provided to first branch road (second branch road of capacitor C21 is connected to first branch road of Node B and capacitor C34) of node C and capacitor C21, and is superimposed on the DC voltage that provided by the first and second multipliers/rectifier circuit 42a, 42b.

Four multiplier/rectifier circuit 42d is similar to the previously described 3rd and the second multiplier/rectifier circuit 42c, 42d, and is coupled to the 4th antenna 2d.The DC voltage exported by four multiplier/rectifier circuit 42d is provided to first branch road of node D and capacitor C12, and second branch road of capacitor C12 is connected to first branch road of node C and capacitor C21.As the result of the RF signal received by the 4th antenna 2d being coupled to four multiplier/rectifier circuit 42d, the DC output voltage of four multiplier/rectifier circuit 42d is superimposed on by the 3rd, second and the DC voltage that exports of the first multiplier/rectifier circuit 42c, 42b, 42a on.Therefore, as the result that the superposition of the output voltage from first, second, third and fourth multiplier/rectifier circuit 42a-42d is arranged, the electromotive force at the first branch road place of the capacitor C12 that the second branch road about capacitor C39 is measured can equal or may higher than 25 volts of DC.As will explaining in further detail, second branch road of capacitor C39 is coupled to " starting fast ", and battery BT2(is also referred to as quick starting voltage device 44), and from four multipliers/rectifier circuit 42a-42d superposition output voltage the DC voltage that provides by battery BT2 raise.

The combination superimposed voltage generated by the multiplier interconnected/rectifier circuit 42a-42d is provided to capacitor C3.Capacitor C3 serves as the temporary storage part 14 of the voltage being detected also rectification for the result as the RF energy received by four reception antenna 2a-2d by four multipliers/rectifier circuit 42a-42d.More particularly, first branch road of capacitor C3 is connected to first branch road of capacitor C12, and second grounding of capacitor C3.Preferably, capacitor C3 is low leakage tantalum capacitor, but can use the capacitor of other memory devices and other types.

As previously mentioned, capacitor C3 is provided to be stored as the DC voltage of the result of RF or the WIFI energy received by four the antenna 2a-2d be attached thereto and the superposition DC voltage that exported by four multipliers/rectifier circuit 42a-42d and the quick startup battery BT2 that raises superimposed voltage at node D temporarily.

Circuit of the present invention also gathers luminous energy preferably by use solar cell 40 and circuit.The Fig. 3 with reference to accompanying drawing should be continued in this respect.In energy acquisition device of the present invention, provide solar cell 40, and exposed by the opening in the main body of the outer cover 32 of described energy acquisition device or the top surface 38 of base 36.Solar cell 40 can generate between about 3.1 volts and about 5.5 volts directly under daylight under room lighting.The negative terminal preferably ground connection of solar cell 40, and the plus end of solar cell 40 is connected to the negative electrode of Zener diode D2, the plus earth of described Zener diode D2.Preferably, Zener diode D2 is 5.6 volt zener diodes to limit the output voltage that provided by solar cell 40 in order to avoid destroy any circuit be attached thereto.

The output of solar cell 40 is connected to the VDD input of power management integrated circuits 46, described power management integrated circuits 46 is such as Cymbet Corporation(Elk River, Minnesota) manufactured by Part No. CBC3112 or any similar management circuit manufactured by many manufacturers.The output voltage of management circuit 46 is conditioned and is chosen to about 4.2 volts, and by isolating diode D3 be provided to main energy storage batteries BT1(that is second or Both primary storage devices 18) positive side so that do not have or insignificant WIFI or RF signal or may be detected time and environment light condition allows by solar cell 40 is around the electric charge on help maintenance battery BT1 when battery BT1 charge.

The electric charge " starting fast " to help or raise on interim holding capacitor C3, uses 3.7 volts, 60 MAHs or higher lithium polymer battery BT2(is see Fig. 3).The minus side ground connection of battery BT2, second branch road of capacitor C39 is then coupled in positive side, so that the superimposed voltage lifting 3.7 volts that the multiplier/rectifier circuit 42a-42d by four interconnection is generated, i.e. the voltage of battery BT2.Correspondingly, the voltage at capacitor C3 two ends is the voltage obtained with the combination of RF or the WIFI energy gathered by circuit of the present invention from the voltage from battery BT2.It should be mentioned that arranging from the superposition of four multipliers/rectifier circuit 42a-42d the 25 volts of DC signals obtained is non-load voltages, and when by underload be used for charging into capacitor C3 time, described voltage can significantly reduce.

Voltage from battery BT2 is used to raise the voltage be temporarily stored on 42d capacitor C3, and supplements the voltage exported by four multipliers/rectifier circuit 42a-42d obtained from collected WIFI and RF energy.In addition, " raising " voltage from battery BT2 assists in ensuring that the second management circuit 48(is see Fig. 3) in its VDD input, there is enough voltage to operate.

According to estimates, when energy acquisition device of the present invention to be stored in darkroom therefore solar cell 40 not formation voltage time, be used as the 60 MAH batteries of battery BT2 by approximate 1500 hours or about 62 days of maintenance, this is because described circuit only draws the electric current of about 25 microamperes to about 40 microamperes from battery BT2.

In order to keep the electric charge on battery BT2, the output voltage that management circuit 46 generates is provided to the anode of isolating diode D50, and the negative electrode of described isolating diode D50 is connected to the positive side of battery BT2.Like this, management circuit 46 serves as the buffering between solar cell and battery BT2, to prevent the overcharge of the battery BT2 that battery may be caused overheated.

Alternatively, in order to charge to battery BT2, just going between of solar cell 40 can be coupled to the positive side of battery BT2 by a diode (not shown), the anode of described diode is connected to just going between of solar cell 40 and the negative electrode of described diode is connected to the positive side of battery BT2.Alternatively; can by PTC(positive temperature coefficient) thermistor (not shown) is connected to battery BT2 between solar cell 40 and battery BT2, so that when just in case its preferably lithium polymer battery of battery BT2() overheated due to overcharge or short circuit provide certain protection for circuit.

Referring again to Fig. 3 of accompanying drawing, will see that the second management circuit 48 is provided and is indirectly coupled to interim holding capacitor C3.Preferably, between the VDD of capacitor C3 and management circuit 48 inputs, arrange house dog monitor circuit 50, as by explaining in further detail.Management circuit 48 can be by Cymbet Corporation(Elk River, Minnesota) the Part No. CBC3112 that manufactures or any similar management circuit manufactured by many manufacturers.The VBAT of management circuit 48 exports the anode being connected to diode D1, as by explaining in further detail.
